WEATHER-STRIP.

Specification of Letters Patent.

Patented (lot. 2%., 19118.

Application filed September 11, 1916. Serial No. 119,446.

To all whom it may concern:

Be it known that I, FREDnnIo G. CoRsnn, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in \Veather- Strips; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple and highly eflicient weather strip for windows, and is particularly directed to the provision of a weather strip for use in connection with sashes which are pivoted, hinged, or otherwise mounted for lateral opening and closing movements, and wherein the weather strip is placed between rabbets and abutting surfaces that move toward and away from each other.

Generally stated, the invention consists of the novel construction and arrangement of parts hereinafter described and defined in the claim.

Heretofore, it has been a common practice to secure weather strips to frames or sash by means of screws, nails, or the like. In such arrangements the fastening devices are usually exposed where they are liable to become loose and, furthermore, in the connection thus made there is liable to be leakage at the attached edge.

In accordance with my invention, the weather strip is secured in place by clamping it between a groove in the body of the sash and a removable strip, such as a stop strip, molding or astragal fitted into the groove. Hereinafter in this specification the term sash is usedin the broad and liberal sense to include the member that moves within a frame to close the opening therein.

In the accompanying drawing a vertical section of a sill, a window frame and the lower edge portion of a casement sash is disclosed.

The construction illustrated in the drawing includes a sash 7 which is hinged to the window frame in the usual manner. This sash is shown in a partly open position. The sill or transom 5 of the frame is provided with a stool 5 over which the lower edge of the sash 7 is arranged to swing. The sash 7 is, at its lower edge, provided with a molding or stop strip 8, which has a flange set into a groove in the sash. This molding 8 may be secured to the sash by nails, screws or in any other suitable manner, and its inner edge is preferably beveled to fit the beveled outer edge of the stool 5".

A weather strip 15, which is of very thin spring sheet metal is interposed between the flange of the molding 8 and the groove in the sash 7, and has a projecting spring blade portion that is normally located at an angle to the beveled edge of said molding and is spaced therefrom. This spring blade portion is adapted to be pressed against the beveled edge of the stool 5* when the sash 7 is closed.

In this arrangement the weather strip is held to the sash in such manner that there is no possibility of leakage of air or water between the stop strip 8 and the part to which it is applied. Also the device or devices which are used for holding the removable strip 8 to the sash or frame, serve directly to hold the weather strip in position. Such a construction is, therefore, not only highly efficient, but cheap and durable, and the device compensates for shrinking, warping and sagging of the sash.

What I claim is:

The combination with a frame having a sill and a stool thereon, of a sash having a grooved lower edge and a stop molding or strip fitted into said groove and having a beveled face for cooperation with a beveled face on said stool, and a sheet metal weather strip interposed and held between said stop strip and its cooperating groove in said sash and having a spring blade projecting at an angle to the beveled face of said strip and adapted to be engaged with the beveled face of said stool by a closing movement of said sash.

In testimony whereof I aflix my signature in presence of two witnesses.

FREDERIC G. CORSER.
